Starting this after 2337.
TL;DR version: I went back and looked at all O's posts that took a position on another player, beginning at 372, and ending when the ball began rolling on the O bandwagon. The pattern I see most clearly (and I dont think it is confirmation bias) is O defending Jo (see red highlights). He mentions a lot of folks, including me a fair bit, but when it comes down to actually taking positions, he's defending/deflecting from Jo.
Here's the long version (my thoughts are in trailing parentheses). My apologies for referring to myself as SFS, but I think it will reduce the potential for confusion long-term:
#372 - Votes Pops for being "Galzria-Confident on steroids" (this was immediately after Pops told everyone to lay off SFS)
763 - "doesn't believe J is mafia"
829 - mildly suspicious of Frisk for indirect accusations
885 - states that Frisk and SFS agree on a lot of things
899 - wants to be reminded of case against Axxle1
906 - admits to defending Dsell
917 - reminds us that we can lynch Pops, because he (O) doesn't like the "old-do-nothing-and-people-will-eventually-forget-I've-acted-crazy-scummy strategy" (two posts later Jo chimes in with "I dont either but you cant argue with the results")
923 - says there doesnt seem to be a case against Axxle1
932 - finds Axxle1's discussion of Mafia theory to be "townish"
944 - says that "barring idiotic actions, won't hammer Axxle1
971 - mentions strawman case against Axxle1, reminds us his vote is still on Pops
978 - says "Theorel is covering himself and deflecting suspicions elsewhere"
982 - votes for Theorel
1192 - says Pops, Frisk and SFS still annoy him
1245 - Links SFS to Frisk again (this is not the first time, though I failed to make note of the previous post number(s), and I am too tired to go back)
1247 - Explains staying off bandwagons because Pops, SFS, and Theorel were "acting incredibly scummily"
1252 - (addressing Jo specifically, and archly): "I'm mafia because I saw past your slightly odd play - Just ask Pops"
1257 - I cant analyze this post very well, but he's taking issue with Galzria' post in 1256, which references MII and Jo's play, and it reads to me as a defense of/deflection for Jo. I'd like for someone to parse this one to see if my read is right, that he's defending Jo.
1260 - This is a Jo post, where Jo notes "how advanced and difficult it is to play like O" and over the next few posts there ensues a lovefest between Jo and O.
1278 - "Dammit J, you make it hard to defend you" (possible humor?)
1347 - Votes for Frisk, says he's already FOS'd Frisk several times
1367 - says SFS is obvTown, but gives SFS an FOBTS
1384 - says SFS would be worst town of all time under the specific condition of Glooble AND SFS being town. Goes further, saying Glooble's play would have been damn terrible if he is town, just not as terrible as SFS's
1449 - Found Galz suspicious until Axxle, Pops, and CF voted for him (Galz), so Galz is less suspicious now
1484 - in responding to SFS's vote on him, says explaining himself (for what SFS noted) would "nearly certainly not be good for the town". (I read this as avoidance at the time, but asked for hypothetical situations where he could legitimately take this position)
1486 - reaffirms SFS's "towniness"
1731 - votes GLooble, says the choice is between Gloob and Pops
1742 - says Pops is dangerous if Mafia
1812 - says "Jo is scumhunting as much as any of us IMO"
1853 - says "If Jo is mafia, he would have been bussed by now"
1878 - says "Jo is obvTown"
1885 - says "SFS and Jo are helpless townie reads.
For these and all the other reasons I've already expressed on Day 2:
VOTE: JOTHEONAH
